Makes it easy to monitor the ammonium/ammonia level in fresh and marine water Ammonium and ammonia mainly arise from fish waste. They are converted into each other depending on the pH value. While ammonium is mostly harmless, ammonia is toxic to fish. The sera NH4/NH3-Test allows monitoring the total concentration of both (the actual ammonia level can be calculated according to the pH value the using the included chart). In case of acute danger, sera toxivec (freshwater) or sera pond toxivec (pond) provide help. sera bio nitrivec (freshwater), sera marin bio reefclear (marine water) or sera pond bio nitrivec (pond) actively counteract lasting enrichment of these substances. Sufficient for approx. 60 measurements.

KW Zone 3 Way Plastic Joint Valve Increase the number of outlets from a single outlet aquarium air pump with the 3 way Aqua One Gang Valve. Easily split the air into 3 outlets so you can run 3 air driven devices at once. Independently control the air flow of each outlet Each valve is adjustable Increase oxygen around the aquarium. Simply connect a piece of airline tubing from the air pump to the SIDE of the gang valve. The air stones or air operated ornament will connect to the TOP of the gang valve with an additional piece of airline tubing. You can turn the knobs on the gang valve to individually adjust the flow to each outlet.

EHEIM CO2 - 230V magnetic valveCO2- magnetic valves (night shut-off) (Solenoid valve)The magnetic valve enables you to switch off the CO2 supply in the aquarium if necessary – e.g. to regulate the pH or overnight.Up to 50% of CO2 can be saved by switching of the supply at night as photosynthesis only takes place in daylight where plants absorb carbon dioxide and release oxygen. At night or without light, the plants consume oxygen, therefore CO2 fertilisation would not be beneficial.The magnetic valve operates with a 230V alternating current and works best when connected to the aquarium light timer. This allows the magnetic valve to be switched off at the same time as the lights.

The Ocean Runner Series of magnetically coupled centrifugal pumps are very quiet in operation. They have fully encapsulated synchronous motors and can operate completely safely either submerged or out of the water. The polished ceramic shaft and bearing is practically wear resistant, ensuring a long operating life. An integrated thermal overheat protection device prevents damage to the windings should the impeller rotation be impeded. The pumps can be easily taken apart for cleaning. All materials are salt water resistant. The Ocean Runner pumps are powerful universal pumps to be used as circulation or current pumps in both salt- and freshwater aquaria. The Ocean Runners are supplied with a rugged pump housing, an energy effi cient motor, a polished ceramic shaft and ceramic bearings. All these qualities ensure a quiet and maintenance free performance for many years. The Ocean Runner pumps are also available in outdoor version with 10 m (c. 32‘) (OR 2500/OR 3500) rubber cable for ponds. OR 1200 – 1 OR- 2500 - 2 OR 3500 – 3 OR -6500 - 4

Aqua Medic Ocean Runner 6500 Impeller Replaceable rotor for the Aqua Medic OR 6500 pump. One of the main parts for the pump pump is the rotor, besides it is the most mobile one, since the rotor always rotates during the pump operation, providing water pumping. Over time, the rotor may fail, this may be evidenced by increased noise or hum of the pump, a drop in the volume of water pumped by the pump. In such cases, the rotor must be replaced.  1 per pack Ceramic shaft and end caps included Genuine Aqua Medic Part Clean the 6500 impeller at every aquarium maintenance to extend its working life and prevent future problems.

CO2-DiffuserThe CO2 gas is atomized into many bubbles by the diffuser. The bubbles create a larger contact surface enabling the CO2 to dissolve quickly in the aquarium water.The bubble counter visually controls the dosing of the CO2. As a rough rule of thumb: approx. 20 mg CO2 per litre. This corresponds to about 10 bubbles per minute per 100 litres of water.EHEIM CO2-diffuser 600for larger aquariums up to 600 lQuality glass CO2 diffuser with separate bubble counter and safe non-return valve for effective and loss-free CO2 dosing.The large diffuser area ensures optimum and effective distribution of CO2 bubbles in large aquariums.
